Transmission method and device for fast switching of micro cells

Abstract

The invention provides a transmission method for quick opening and closing of a micro cell. The method comprises the steps that when it is detected that no data interaction exists between a terminal and a micro cell base station, the terminal is informed that the micro cell base station is about to enter the closing state; when the micro cell base station is in the closing state, if uplink data at the terminal need to the transmitted, the terminal judges whether the micro cell base station enters the opening state or not according to received indication information of the micro cell base station; when the micro cell base station is in the closing state, if downlink data at the micro cell base station need to be transmitted, the terminal is informed that the micro cell base station is about to enter the opening station, and the terminal is informed of the duration time spent by the micro cell base station in the opening state. Correspondingly, the invention further provides a transmission device for quick opening and closing of the micro cell. According to the technical scheme, the terminal can be efficiently informed of the opening and closing states of the service base station in time, the terminal is prevented from conducing ineffective detection, and power consumption of the terminal is saved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to a transmission method for fast switching of micro cells and a transmission device for fast switching of micro cells. Background technique [0002] In the current wireless communication system, in order to further increase the capacity of the network, the miniaturization of the base station and the densification of the network nodes have become an inevitable choice. However, the densification of network nodes will inevitably bring about the problem of mutual interference, and strong interference between nodes will greatly affect the performance of the system. [0003] In order to solve the interference problem between low-power nodes, 3GPP has done a lot of standardization work. In the R10 / 11 stage, the ABS (Almost Blank Subframe, almost blank subframe) method is introduced for the scenario where the macro base station and the low-power base station work at the same fr...

Problems solved by technology

Among them, the solution of quickly switching small cells has been proven to obtain optimal system performance. However, fast small cell switching will affect the measurement and other behaviors of the terminal. Therefore, how to let the terminal obtain the current network status in time, including on / off state, the length of time in the on state and how to obtain CSI (ChannelState Information, channel state information) information in the off state need to be resolved
